I was asked to take some shots of a community event that happened this morning where I live.

I brought my 1DsII, 1DIII and my 6D with me, which was a good thing, because the 6D gave me nothing but grief today.

I'd take a shot with the 6D, hear a horrible noise, and then the cam would either fail to take the shot and display an ERR message suggesting a miscommunication with the lens, or it would take the shot, and not take any others until I powered off and back on again.

If the cam took the shot, immediately afterwards, the viewfinder would go half dark. Removing the battery would return the viewfinder to a clear image.

I'm not sure what's really going on, but this camera is going back to Canon after I can make it reproduce the results I got.

After getting home, the camera appears to be working ok again and I can't get it to duplicate the problem.

It's frustrating, but at least I have backup cameras I can use and trust, while this problem gets sorted out.

I'll post back in this thread after I've reviewed the shots on my computer.

Bummer and ever so frustrating...............good thing for backups!
Mine is in the hands of Canon right now, just got conformation of 'under warranty' repair but don't know yet what they are doing for the fix yet.
Your problem is totally different than my exposure issues but much more severe in resulting use of camera.............but I don't have a back up Wait, I have an iPhone and an PNS Canon so I am good but can't put on my lenses

Hope you can produce a duplicate issue and get it resolved quickly.......keep us informed

My 5DII randomly (it had been working fine) failed five minutes into the ceremony of a wedding I was shooting (turned out it needed a new shutter assembly with only 30K clicks on the camera). I had my 60D with me as a backup and only missed 7 minutes of shooting time.

Cameras fail. Sh$t happens. That's why we have more than one body with us when we shoot professionally.

This was a hardware failure, not problems with the performance of the 6D as a camera. It could have happened to any model, they all suffer failures occasionally.
^^^ Agree. Professional bodies fail too. I busted a shutter on one of my 1Ds II just at a wedding last weekend, switched to the other body kept shooting as if nothing happened. Now it's on its way to CPS, business expenses, all good. This is why we get paid.

I'll chime in. I sent in my 5d2 and 7d for new shutters b4 a Southern Caribbean trip so I wouldn't have any troubles with them. The new shutter on the 7d began to have problems the 2nd day of the trip. Canon repaired it upon return, but any problems can be frustrating. Hopefully they can replicate and fix your problem quickly. It takes a while to trust the camera again after a failure/fix happens.

I had a Canon 18-200mm IS that randomly made a horrible noise and gave an error msg
- I could only replicate it by putting it on continuous shooting at a small aperture value - the blades worked fine during normal shooting but couldn't keep up for rapid shooting (this was on a 50D at 6fps)

Trouble is, threads like this, threads from inexperienced uses of 5DII's complaining of banding and all the other poorly informed threads still get picked up by Google and mountains are made out of molehills
